摘要:
The apparatus comprises an input memory 102 for storing data necessary for geometrical operations, such as coordinate transformation, luminance calculation, and clipping operation of graphics; a global bus connected to the input memory; a plurality of floating process memories connected to the global bus, for receiving data necessary for geometrical operations; a sequencer for transmitting data necessary for geometrical operations, stored in the input memory, to the plurality of floating process memories; and a plurality of floating processing units each connected to a respective one of the plurality of floating process memories, for independently executing geometrical operations, using data transmitted from the floating process memories.
